Answer 1

Answer:

a) 1- placenta

2-Uterus

3- Vagina

4- Foetus

b) The placenta is an organ that develops in your uterus during pregnancy. This structure provides oxygen and nutrients to your growing baby and removes waste products from your baby's blood. The placenta attaches to the wall of your uterus, and your baby's umbilical cord arises from it.

c)During pregnancy, the lining of your uterus thickens and its blood vessels enlarge to provide nourishment to the fetus. As pregnancy progresses, your uterus expands to make room for the growing fetus. By the time your baby is born, your uterus will have expanded to many times its normal size.

d)Sorry idk please check google.

*maybe- Pregnancy lasts for about 280 days or 40 weeks.
